摘要

在某些情况下，医院可能会遇到氧气相对短缺的问题，例如未来的大流行病、自然灾害或战时。我们对家用呼吸机进行了改装，将通常在呼气时排入大气的氧气收集起来，输送给病人。与不进行改装的情况相比，改装后可明显提高机械通气患者在基线 FiO2 和基线 FiO2 +1 、 +2 和 +3 L/min 时的 PaO2。在保持 PaO2 的情况下，改良后的壁面耗氧量减少了中位数（IQR）-1.0（-1.25 至-1.00）升/分钟。在氧气相对短缺的情况下，这种改良方法可能很有价值。

In vivo assessment of a modification of a domiciliary ventilator which reduces oxygen consumption in mechanically ventilated patients.

There are instances where hospitals may experience a relative shortage of oxygen, for example, future pandemics, natural disasters or wartime. We developed a modification to a domiciliary ventilator that captures oxygen normally vented during expiration into the atmosphere, delivering it to the patient. The modification significantly increases PaO₂ in mechanically ventilated patients at their baseline FiO₂ and baseline FiO₂ +1, +2 and +3 L/min compared to no modification. The modification reduces walled oxygen consumption by median (IQR) -1.0 (-1.25 to -1.00) L/min whilst maintaining PaO₂. This modification may be a valuable in circumstances where there is a relative shortage of oxygen.

期刊介绍： The Journal of the Intensive Care Society (JICS) is an international, peer-reviewed journal that strives to disseminate clinically and scientifically relevant peer-reviewed research, evaluation, experience and opinion to all staff working in the field of intensive care medicine. Our aim is to inform clinicians on the provision of best practice and provide direction for innovative scientific research in what is one of the broadest and most multi-disciplinary healthcare specialties. While original articles and systematic reviews lie at the heart of the Journal, we also value and recognise the need for opinion articles, case reports and correspondence to guide clinically and scientifically important areas in which conclusive evidence is lacking. The style of the Journal is based on its founding mission statement to ‘instruct, inform and entertain by encompassing the best aspects of both tabloid and broadsheet''.
